Abstract
Acute genital diseases can occur at any age and are characterized by complaints of various kinds of the external genitalia. Pain, swelling, and redness of the scrotum, adjacent groin region, and immediate surroundings are the leading symptoms, the severity of which may vary. In addition, peritonitic symptoms such as nausea, vomiting, and circulatory sensations may be present and are comparable to symptoms of an acute abdomen. The term "acute scrotum" encompasses various clinical entities, where scrotal symptoms are predominant and represent a urological emergency situation. Immediate and comprehensive diagnostics are necessary to ensure timely management in case of necessary surgical intervention.

Abstract
PURPOSE Ultrasound as a diagnostic tool in suspicion of testicular torsion is still highly debated. In this investigation, we aimed to evaluate whether time spent on scrotal ultrasonography had a negative impact on testicular loss. METHODS Patients' records containing a scrotal ultrasound and/or surgical procedure codes for testicular interventions on suspicion of testicular torsion were examined. Patients aged 0-15 years admitted during 2015-2019 at Copenhagen University Hospital, Rigshospitalet were included. RESULTS In total, 1566 patients underwent an ultrasound and 142 of these proceeded to surgery while 13 patients proceeded directly to surgery without an ultrasound. The rate of testicular loss with a preceding ultrasound was 23% versus 42% without (p = 0.18). Four cases of testicular torsion were misdiagnosed by ultrasound resulting in a sensitivity of 95.4% and specificity of 95.6%. The mean diagnostic delay from ultrasound examination was 55 ± 39 min, and the mean time from ultrasound to surgery was at 169 ± 76 min versus 171 ± 72 min without ultrasound. CONCLUSION In a clinical setting, ultrasound provided a reliable tool for the diagnosis of testicular torsion and did not seem to increase the orchiectomy rate.

Abstract
INTRODUCTION The Testicular Workup for Ischemia and Suspected Torsion (TWIST) score was created to help physicians in the clinical evaluation of acute scrotum in which testicular torsion (TT) is suspected. There have been only a few reports on validation of the TWIST score since the original study was published. OBJECTIVES To validate the TWIST score as a scoring system. PATIENTS AND METHODS We reviewed the records of 106 patients with acute scrotum in our prospectively maintained database. The patients were divided into two groups by the final diagnosis: testicular torsion (group TT) or non-testicular torsion (group NTT). We retrospectively calculated the TWIST score of the patients. Patients were divided into low (0-2), intermediate (3-4), or high (5-7) risk groups according to the total score. RESULTS Fifteen patients (14%) had TT. The median age at presentation was 13.3 years (range 1.6-16.2) in group TT and 10.4 years (range 0.25-18.9) in group NTT, respectively. The sensitivity of clinical and Color Doppler ultrasonography (CDUS) findings to diagnose TT was 100%, whereas the specificity was 93.4%. Positive predictive value (PPV) and negative predictive value (NPV) were 71.4% and 100%, respectively. According to the calculated TWIST score, 65, 23, and 18 patients belonged to low, intermediate, and high risk groups, respectively. TT was found in 1(1.3%), 3(13%), and 11 (61%) patients of low, intermediate, and high risk groups, respectively. The NPV of the TWIST score for the low risk group was 98.5%, whereas the PPV of the TWIST score for the high risk group was 61.1%. Among the four patients with TT in low risk and intermediate risk groups, three patients presented to our institutions within 6 h after the onset. The torsion was 180° in two of the three patients. CONCLUSION The TWIST score can be useful for clinical diagnosis of testicular torsion, but is inferior to clinical findings along with CDUS. We should consider the possibility that a TWIST score could be underestimated when patients present with acute scrotum immediately after onset or the affected testis is mildly twisted.

Abstract
The British Association for Sexual Health and HIV (BASHH) UK guideline for the management of epididymo-orchitis has been updated in 2020. It offers advice on diagnostic tests, treatment and health promotion principles in the effective management of epididymo-orchitis. Empirical treatment should be started in patients with objective swelling and tenderness on testicular examination. First-line empirical treatment for sexually acquired epididymo-orchitis has changed to ceftriaxone 1g intramuscularly and doxycycline. Higher dose of ceftriaxone in line with the BASHH 2018 gonorrhoea guideline ensures effective treatment of strains with reduced susceptibility. Ofloxacin or doxycycline is recommended in patients with epididymo-orchitis probably due to non-gonococcal organisms (e.g. negative microscopy for gram-negative intracellular diplococci or no risk factors for gonorrhoea identified). Where Mycoplasma genitalium is tested and identified, treatment should include an appropriate antibiotic (e.g. moxifloxacin). If enteric pathogens are a likely cause (e.g. older patient, not sexually active, recent instrumentation, men who practice insertive anal intercourse, men with known abnormalities of the urinary tract or a positive urine dipstick for leucocytes and nitrites), ofloxacin and levofloxacin are recommended. A clinical care pathway has been produced to simplify the management of epididymo-orchitis. A patient information leaflet has been developed.

Abstract
Acute testicular pain in childhood can be caused by testicular torsion, torsion of the appendix testis, or epididymo-orchitis. Quick and reliable diagnosis is essential for determining the further course of action (surgery or conservative approach). The diagnostic tool of choice is high-resolution sonography with a linear transducer (> 10 MHz) combined with color and spectral Doppler sonography. The Doppler device settings should include a low pulse repetition frequency (< 4 cm/s), a low wall filter (< 100 Hz), and adequate gain. Comparison with the unaffected healthy testis is essential. The most important of the three diseases is torsion of the spermatic cord because it requires immediate surgical intervention and detorsion. The affected testis is enlarged and has an inhomogeneous echotexture with hypoechoic and hyperechoic areas as well as an associated hydrocele. In testicular torsion, color Doppler shows reduced or absent intratesticular vessels in comparison with the healthy contralateral testis. Spectral Doppler shows decreased flow velocities especially during diastole in intratesticular arteries and an increased resistance index. The investigation should always include imaging of the spermatic cord from the outer inguinal ring to the upper pole of the testis. In contrast to a normal finding, the vessels and the ductus deferens are not displayed as linear tubular structures but in form of a spiral twist. Ultrasound shows a target-like structure with multiple concentric rings. Color Doppler sonography shows the typical whirlpool sign. In torsion of the appendix testis, the appendix testis is enlarged in the groove between the testis and epididymis. The longitudinal diameter of the appendix testis can be greater than 5 mm. The echogenicity of the torsed appendage can vary between hypoechoic (acute torsion) and hyperechoic (prior torsion). An associated hydrocele of varying size is usually seen. Color Doppler sonography reveals a lack of perfusion of the enlarged appendix testis and increased vascularity of the testis and primarily the epididymis. Epididymo-orchitis is characterized by an enlarged epididymis and/or testis with inhomogeneous echogenicity (hypoechoic - hyperechoic). Color Doppler sonography shows increased vascularity in comparison with the unaffected testis. Spectral Doppler reveals increased diastolic flow velocities and a decreased resistance index. Idiopathic scrotal edema and an incarcerated inguinal hernia must be ruled out in the differential diagnosis.

Abstract
INTRODUCTION Ultrasound is a valuable tool in establishing the cause of acute scrotum pain. However, its role in testicular torsion (TT) detection remains controversial. This review aims integrate pre-existing data to assess the value of B-mode and colour Doppler ultrasound (CDS) features combined in the detection of TT in acute scrotum pain patients of all ages. METHODS A search through electronic databases, grey literature and hand searching using specific search terms was conducted to identify relevant literature. Search results were subjected to a three-step selection process to ensure the inclusion criteria of this review were met. Statistical data pertaining to the accuracy, sensitivity, and specificity of the B-mode, CDS and combined B-mode CDS features were extracted. These results subsequently underwent a narrative analysis. RESULTS Five studies met the inclusion criteria. A variety of B-mode features were identified. Most studies showed that reliance on CDS alone can be prone to false-negative results. The combination of B-mode and CDS features were found to increase the overall sensitivity of ultrasound towards TT (up to 100% in 3 studies). All studies recommended correlation with clinical examination findings. Several limitations in methodology of the included studies were noted: small sample populations and lack of information on the experience of ultrasound practitioners. This highlighted the need for a primary study with a larger sample population to validate the findings of this review. CONCLUSION The combination of B-mode and CDS ultrasound is a useful and reliable triage tool in the detection of TT, particularly in equivocal or low suspicion cases but its findings should always be adjunct with clinical examination. Nevertheless, it is noted that appropriate service level agreements, pathways, and training are key factors in ensuring effectiveness of the process. IMPLICATIONS FOR PRACTICE Dedicated training and appropriate departmental protocol are key in ensuring accurate diagnosis across all levels of practice.

Abstract
Acute scrotal pain is one of the most frequent symptoms in pediatric patients visited in the Emergency Department. Ultrasonography with color and power Doppler represents the first-line method that clinicians use to carry out the differential diagnosis between spermatic cord torsion and inflammation, but sensitivity and specificity are 63-100% and 97-100%, respectively; this variability may be related to operator's experience and testis vascular hemodynamics and also to machine performance and patient age. Recent technological innovations have made possible to create a new Doppler mode called ultrasound microvascular imaging. This technique exploits algorithms capable of separating low frequencies of static tissue artifacts from ones of very weak flows. It is known as MicroV (from Esaote) and Superb microvascular imaging (from Toshiba). It provides both macrocirculation vascular maps, as a typical Doppler feature, and microcirculation vascular maps. Furthermore, the use of background subtraction could improve the visibility of small vascular structures. We report a case of a pediatric patient suffering from acute scrotal pain assessed ultrasonographically with this innovative Doppler technique (MicroV) that may give more confidence in detecting testicular vascular signals if compared with traditional Doppler techniques.

Abstract
INTRODUCTION Acute scrotum is a common presentation to the pediatric emergency department, and ultrasound is frequently used to narrow the differential diagnosis. Point-of-care ultrasound (POCUS) is increasingly used by urologists and emergency physicians and could potentially be used to detect pediatric testicular torsion. OBJECTIVES This study aimed to determine the accuracy of POCUS by pediatric emergency physicians in diagnosing testicular torsion and the agreement between point-of-care ultrasound and final diagnosis for other causes of acute scrotum. STUDY DESIGN A chart review of patients presenting to the study emergency department who received POCUS by a pediatric emergency physician, as well as radiology department ultrasound and/or surgery, was performed. Charts were reviewed for POCUS diagnoses, final diagnoses, and imaging time metrics. RESULTS A total of 120 patients met study criteria, with 12 cases of testicular torsion. The diagnostic accuracy of POCUS for testicular torsion is described in the summary table. For all causes of acute scrotum, point-of-care ultrasound agreed with final diagnosis in 70% (95% confidence interval [CI] 62-78%) of cases, and more experienced point-of-care ultrasound users displayed higher agreement with final diagnosis. Point-of-care ultrasound results were generated a median of 73 min (Q1 = 51, Q3 = 112) before radiology department ultrasound results. DISCUSSION Scrotal POCUS performed by pediatric emergency physicians appears to be an accurate tool to detect testicular torsion in children with acute scrotum and saves time compared with radiology ultrasound. The study results may not be generalizable to hospitals without a multidisciplinary POCUS system for quality assurance and image sharing. Future work on POCUS for acute scrotum should investigate its impact on patient outcomes, cost-effectiveness, and family satisfaction. CONCLUSION Point-of-care ultrasound by pediatric emergency physicians is accurate for detecting testicular torsion in children with acute scrotum and could expedite diagnosis of this time-sensitive condition.

Abstract
OBJECTIVE Acute scrotal pain is a common presentation to the paediatric emergency department. Testicular torsion is one of the most common causes of acute scrotal pain. Testicular torsion is a surgical emergency requiring immediate surgical exploration to prevent permanent testicular damage or loss. The aim of this study was to determine the surgical outcome of all scrotal explorations and to assess the use of colour Doppler ultrasound (CDUS) in the assessment of acute scrotal pain in two tertiary referral paediatric units. MATERIAL AND METHODS A retrospective review of a prospectively maintained database was carried out for all scrotal explorations between 1999 and 2010. RESULTS In total, 155 scrotal explorations were carried out for acute scrotal pain. The mean age was 9.1 years (range 0-15 years). The pathology in 46.5% (n = 72) was testicular torsion, 30.3% (n = 47) were torsion of a testicular appendage, 16.1% (n = 25) were epididymitis, 3.3% (n = 5) had no obvious pathology identified and other pathology accounted for 4%. There was a significant difference in age of presentation between those with testicular torsion and those with torsion of a testicular appendage (9 vs 10 years, p = 0.0074). CDUS was performed by a trained radiologist on 40 patients. Overall sensitivity, specificity, positive predictive value and negative predictive value for CDUS predicting testicular torsion were 96.9%, 88.9%, 96.9% and 89%, respectively. Overall, 36 patients (23%) with acute scrotal pain (50% of patients in the group with confirmed testicular torsion at exploration) required orchidectomy. CONCLUSION This study supports the practice of immediate surgical exploration with a clinical suspicion of testicular torsion in a paediatric population.

Abstract
BACKGROUND The acute scrotum in childhood or adolescence is a medical emergency. Inadequate evaluation and delays in diagnosis and treatment can result in irreversible harm, up to and including loss of a testis. Various diseases can produce this clinical picture. The testis is ischemic in only about 20% of cases. METHODS This review is based on a selective literature search, the existing clinical guideline, and the authors' experience. RESULTS The clinical approach to the acute scrotum must begin with a standardized, rapidly performed diagnostic evaluation. Dopper ultrasonography currently plays a central role. Its main use is to demonstrate the central arterial blood supply and venous drainage of the testis. The resistance index of the testicular vessels should also be determined. CONCLUSION Physical examination and properly performed Doppler ultrasonography enable adequate evaluation of the acute scrotum in childhood and adolescence. In the rare cases of diagnostic uncertainty, immediate surgical exposure of the testis remains the treatment of choice.

Abstract
The BASHH UK guideline for the management of epididymo-orchitis has been updated in 2010. Consideration should be made of the changing potential aetiologies of epididymo-orchitis - mumps in non-immune individuals and tuberculosis in the immunocompromised and men from countries of high prevalence. The treatment of sexually acquired epididymo-orchitis has changed given the high levels of quinolone-resistant gonorrhoea such that ceftriaxone and doxycycline are recommended in those at high risk of gonorrhoea and doxycycline or ofloxacin in those patients where gonorrhoea is considered unlikely (negative microscopy for Gram-negative intracellular diplococci and no risk factors for gonorrhoea identified). A clinical care pathway has also been produced to simplify the management of epididymo-orchitis.

INTRODUCTION Testicular torsion in children is found both in neonates [perinatal testicular torsion (PTT), <30th day of life] and in older children [testicular torsion (TT)]. Prediction of testicular viability is essential for deciding whether to perform emergency exploration surgery. The aim of the present study, therefore, was to investigate the sonomorphological parameters as predictors for testicular viability. MATERIALS AND METHODS All our cases of sonographically diagnosed and surgically confirmed testicular torsion (n = 25) in a 7.5-year period were reviewed. We evaluated the overall group and two subgroups, PTT (n = 9) and TT (n = 16), and assessed the following sonomorphological parameters: normal echogenicity (homogeneous), diffuse hyper-/hypoechogenicity (homogeneous) and focal hyper-/hypoechogenicity (heterogeneous). These findings were correlated with the testicular recovery rate. RESULTS In both groups, we found the highest recovery rates in testes with normal, homogeneous echogenicity and a zero recovery rate in testes with heterogeneous echogenicity (p = 0.0117). CONCLUSIONS By using the sonomorpohological criteria presented here, testicular viability can be appraised in all age groups to help determine the prognosis for testicular outcome. In PTT, a nonperfused, homogeneously appearing testis represents the initial phase of torsion. Only for this type is there hope for salvage. In addition to the intraoperative appearance, a testis that is preoperatively heterogeneous in appearance can support the decision for orchiectomy.

Abstract
The purpose of this study was to assess the clinical presentation and ultrasonographic findings of acute scrotum in young males. A total of 87 patients (<or= 25 years old) with presentation of acute scrotum were retrospectively analyzed in Kaohsiung Medical University Hospital. The patients were divided into three groups according to their final diagnosis: 41 patients with testicular torsion (TT), eight patients with torsion of the testicular appendage (TTA), and 38 patients with epididymo-orchitis (EO). The mean ages of the TT group (14.0 +/- 5.7 years) and EO group (16.6 +/- 7.6 years) were higher than that of the TTA group (10.0 +/- 3.5 years) (p = 0.02). White blood cell count (> 10,000 cells/microL) was not found to be statistically different among groups. Pyuria was found in 10 (26%) patients with EO. Color Doppler ultrasound has high sensitivity (87.9%) and specificity (93.3%) rates to differentiate TT from other causes of acute scrotum. In cases with a lower risk of TT, we suggest that a technically adequate color Doppler ultrasound may be arranged to help differentiate diagnoses and prevent needless surgery. The importance of emergent management for acute scrotum should also be impressed upon the public through education to avoid delayed presentation to medical facilities.

Abstract
BACKGROUND Investigation of the value of scrotal Doppler ultrasound (DUS) in the diagnosis of acute scrotum and its impact on the treatment strategy was undertaken. METHOD Seventy-nine children (mean age, 9.2 years) with acute scrotum were prospectively studied. The protocol included history, clinical examination, scrotal DUS, and standard laboratory analysis. Depending on scrotal DUS findings, the children were treated either nonoperatively (normal or increased testicular blood flow) or surgically (reduced or absent testicular blood flow). A follow-up investigation 6 weeks after discharge included a scrotal DUS. RESULTS In 66 children (84%), the result of DUS determined the management; 26 children with hyperperfusion (epididymitis and orchitis), 18 children with appendix testis torsion (ATT), and 9 children with normal perfusion (edema and hematoma) were treated nonoperatively. The follow-up examination revealed no testicular atrophy and confirmed the primary diagnosis. Ten children without testicular perfusion and suspected torsion and 3 children with orchitis and pyocele were surgically explored, and again, the initial DUS diagnosis was verified. In the remaining 13 patients (16%), the result of the ultrasound examination was unclear. Of these, 6 children were noncompliant and refused to undergo ultrasonography. Another 4 children were explored because of persistence of symptoms. In 3 additional patients, a testicular tumor was suspected. All these 13 children underwent surgical exploration, revealing inflammation (epididymitis) in 6 children and acute ATT in 4 children, whereas the suspected tumor emerged as postacute ATT in 3 boys. CONCLUSION In 84% of children with acute scrotal pain, the DUS was able to differentiate between surgical emergencies and other etiologies. In 16% of our pediatric patients, the DUS remained unclear, thereby necessitating surgical exploration.

Abstract
Acute scrotum represents an emergency situation although testicular torsion is present in less than 20% of the cases. Sonography has meanwhile become the definitive modality for diagnosis. Its increasing use before surgical intervention has led to technical improvements in ultrasound diagnostics and critical assessment of ultrasound criteria to exclude testicular torsion as well as standardization of examination procedures. Central arterial and venous perfusion shown to be bilaterally equal on Doppler sonography is the most important criterion for excluding torsion. This article discusses other criteria such as the "resistance index," comparison of parenchymal structure of both testes, evidence for spermatic cord torsion, or differences between the sides in perfusion of the testicular parenchyma and highlights the difficulties involved in partial and intermittent testicular torsion. Alternative investigative methods and the significance of sonography in the differential diagnosis of other underlying causes are addressed. In summary, the combination of interpreting B-mode imaging, color Doppler, and power Doppler sonography and analyzing Doppler flow curves after clinical examination results in successful and conclusive evaluation of the testes in cases of acute scrotum in boys.

Abstract
Acute testicular torsion in children is an emergency and has to be diagnosed urgently. Doppler sonography is increasingly used in imaging the acute scrotum. Nevertheless, in uncertain cases, surgical exploration is required. In this study, we attempted to define the role of Doppler sonography in the diagnostic workup of the acutely painful scrotum. All patients admitted between 1999 and 2005 with acute scrotal pain were included. After clinical assessment, patients were imaged by Doppler sonography with a ''high-end'' instrument. In cases of absent arterial perfusion of the testis in Doppler sonography, surgical exploration was carried out. Patients with unaffected perfusion were followed clinically by ultrasound for up to 2 years. Sixty-one infants and children aged 1 day to 17 years (median: 7.9 years) were included. In 14 cases, sonography demonstrated absent central perfusion, with abnormal parenchymal echogenicity in six. Absence of venous blood flow together with reduction of central arterial perfusion was found in one infant. In these 15 patients, surgical exploration confirmed testicular torsion. Among the other 46 patients, we found four cases with increased testicular perfusion and 27 with increased perfusion of the epididymis. In one infant, a testicular tumour was found sonographically, and orchiectomy confirmed diagnosis of a teratoma. Follow-up examinations of the conservatively treated patients showed good clinical outcome with physiologic central perfusion as well as normal echogenic pattern of both testes. No case of testicular torsion was missed. By means of Doppler sonography, an unequivocal statement regarding testicular perfusion was possible in all cases. The initial Doppler diagnosis was confirmed by operative evaluation and follow-up ultrasound. Testicular torsion can therefore be excluded by correctly performed ultrasound with modern equipment.

Abstract
The acute scrotum in the paediatric population is a clinical dilemma where a definitive diagnosis can only truly be made at surgical exploration. We postulate that surgical exploration in all cases allows truly accurate diagnoses, treats the torted appendage testes and enables the validity of clinical signs associated with scrotal pathology to be assessed. We retrospectively reviewed all boys less than 15 years old who presented to our institution with scrotal pain over a 2 year period. A total of 121 patients attended of whom 113 had exploratory surgery, 31 (27%) had testicular torsion, 64 (57%) had a torted appendage testis, 12 (11%) had epididymitis, 1 (1%) had fat necrosis and 5 (4%) had no abnormality detected. On exploration 9 (29%) of the torted testis were unsalvageable and thus required excision. The initial clinical impression was frequently demonstrated to be flawed. Two patients with testicular torsion presented with a painless swelling and two further patients had necrotic testes despite a history of pain for less than 4 h. A normal cremasteric reflex and a visible blue dot were detected in boys with testicular torsion. Doppler ultrasound scans were not reliable with 50% sensitivity to clearly differentiate between torsion of the testis and that of the appendage testis. Absolute dependence on clinical features can lead to a misdiagnosis of testicular torsion. The surgical treatment of torted appendage testis is safe, allowing accurate diagnosis and pain relief with minimal morbidity. Early scrotal exploration of all cases with testicular pain ensures maximal testicular salvage.

Abstract
BACKGROUND/PURPOSE The aim of this study was to present the current experience and evidence relating to surgical evaluation and management of nonrenal genitourinary presentation in children with Henoch-Schönlein purpura (HSP). Henoch-Schönlein purpura is the most common systemic vasculitis in childhood. Presenting symptoms include a rash, arthralgia, abdominal pain, and, frequently, renal involvement. Genitourinary symptoms are infrequently reported; however, surgical evaluation is often required. METHODS A MEDLINE literature search of the last 3 decades was conducted using the terms Henoch-Schönlein purpura in combination with acute scrotum or genitourinary, genital, or related symptoms as the keywords. Reference lists of retrieved articles were reviewed for further relevant articles. Case reports were included when no larger case series were found. Articles of foreign language were included if abstracts proved sufficient information. RESULTS Genitourinary manifestations are mainly anecdotally reported. Scrotal pain and swelling were the most frequent nonrenal genitourinary symptoms reported in children with HSP, occurring in about 13% of boys evaluated for HSP. No prospective, population-based reports on genitourinary manifestations in HSP were found, thus making estimation of the true incidence difficult. CONCLUSIONS A wide variety of nonrenal genitourinary pathology may be expected by surgical evaluation of patients with HSP. Most cases are self-limited in nature. Scrotal symptoms are frequent, but testicular torsion is highly unlikely when the diagnosis of HSP is established. Clinical vigilance should be paid to patients with possible obstructive ureteritis, for whom prompt surgical intervention may be indicated.

Abstract
Varicocele rupture was diagnosed in a 23-year-old man who presented with swelling and pain in the left scrotum after sexual intercourse. Color Doppler ultrasonography revealed blood flowing into the space surrounding the left testis, a hematoma and reflux of blood in the left spermatic vein. Varicocele rupture is a very rare condition and there have been only five reported cases.

Abstract
BACKGROUND Traditionally, every patient with an acute scrotum needed surgical exploration for definitive exclusion of testicular torsion. OBJECTIVE In this study, we aimed to evaluate the improved accuracy in clinical diagnosis with colour Doppler Ultrasonography (US) added to normal clinical assessment. MATERIALS AND METHODS We retrospectively reviewed 626 patients, who presented with acute scrotal pain between January 1998 and June 2004. Following history and physical examination, the patients either proceeded directly to surgery or underwent US examination. If clinical suspicion of testicular torsion persisted after US, the patients would still undergo scrotal exploration. RESULTS Of the 294 patients who had routine scrotal exploration without preliminary US, only 23 (7.8%) were found to have testicular torsion. Amongst the 332 cases that had initial US, 9 (2.7%) patients revealed testicular torsion that was confirmed at subsequent surgery. The remaining 323 patients had initial negative US, but 29 were explored eventually on clinical indications. Of these, 4 (1.2% of 323) cases were diagnosed intra-operatively as testicular torsion. None of the remaining 294 patients who were managed conservatively proved to have testicular torsion after a minimum follow-up of 2 weeks. For testicular torsion, US yielded a sensitivity of 69.2% (95% confidence interval =38.9-89.5), specificity of 100% (95% CI=98.5-100), positive predictive value of 100% and negative predictive value of 97.5%. CONCLUSIONS US has proven to decrease the number of emergency scrotal explorations, length of hospital stay and hence reduce the cost of management of acute scrotum.

Abstract
OBJECTIVE To determine the relative importance of clinical presentation, laboratory studies, and ultrasonography in the diagnosis of acute scrotum, and to suggest an effective method of management. SUBJECTS AND METHODS Forty patients who were hospitalized between January 2002 and December 2002 for acute scrotum were studied with respect to history, physical examination, blood tests, urine analysis including culture, and scrotal ultrasonography with color Doppler study. RESULTS Epididymitis (n = 24) was the commonest cause of acute scrotum followed by testicular torsion (n = 11), torsion of testicular appendages (n = 4), and idiopathic scrotal edema (n = 1). Both mean age (40.7 vs. 13.8 years), and average duration of pain at presentation (4.5 days vs. 19.1 h) were higher in patients with epididymitis than in torsion. Onset was usually insidious in epididymitis, sudden in testicular torsion, and variable in torsion of testicular appendages. The majority (87.5%) of patients with epididymitis were managed conservatively. The testis was salvaged in 81.8% of patients with testicular torsion. The accuracy of ultrasonography was only 72.7% in testicular torsion, but was good in epididymitis. CONCLUSION Our results show that a careful clinical evaluation, by an experienced examiner, provides the correct diagnosis in acute scrotum rather than ultrasonography. It is of utmost importance to exclude testicular torsion in those who are younger than 16 years and whose pain duration is less than 24 h.

Abstract
Acute scrotal pain makes up approximately 0.5% of all complaints presenting to an emergency department. Some of the most com-mon diagnoses for this complaint are testicular torsion and epididymitis. Misdiagnosing testicular torsion can lead to organ loss,cosmetic deformity, and compromised fertility. Modem ultrasound examination of the scrotum is the test of choice for acute scrotal pathology and yields high accuracy compared with surgical exploration. A key component of the testicular examination is use of power and spectral Doppler ultrasonography. Examination of the acute scrotum should not be undertaken unless Doppler capability is available because the evaluation of blood flow is such an important part of diagnosis of testicular torsion, orchitis, epididymitis,trauma, and hemorrhage into a mass.

Abstract
BACKGROUND The purpose of the present study was to evaluate the historical features and physical examination findings in boys presenting with acute scrotum and to determine the reliability of these modalities to make the correct clinical diagnosis. METHODS A retrospective review of all boys presenting with acute scrotal/testicular pathology between January 1994 and December 1998 was performed. RESULTS Two hundred and four boys were included in the study: 110 with torsion of the testicular appendage (TA), 40 with testicular torsion (TT), 29 with epididymo-orchitis (EO) and 25 with other diagnoses. Seventeen boys were managed conservatively. With the exception of symptom duration, there was no statistically significant difference between boys with TA, TT and EO. Boys with TT sought medical attention significantly earlier (median: 9.5 h) than those with TA (median: 48 h). Boys requiring an orchidectomy (n = 8) presented later than those who did not (median 30 vs 9 h; P < 0.05): seven (88%) were under 7 years of age. The testicular salvage rate was 88% and 36% with a pain duration of <12 h and >12 h, respectively. The preoperative clinical diagnosis was correct in 80% of those boys who underwent surgical exploration. Testicular torsion was misdiagnosed clinically in five boys. Late testicular atrophy was not observed in the present study. CONCLUSIONS Most boys presenting with acute scrotum have TA. The history and physical examination can reliably identify those boys who can be managed conservatively. Routine surgical exploration is no longer justified in all boys with acute scrotum.

Abstract
Color Doppler ultrasound has been the mainstay for the evaluation of the scrotum in a variety of clinical settings. However, ultrasonography results are not always accurate or conclusive. Despite the high cost and limited availability, magnetic resonance imaging with the dynamic contrast-enhanced subtraction technique provides accurate information on morphology as well as blood flow. Infrared scrotal thermography increases accuracy in the diagnosis of varicocele. This article attempts to summarize recent advances in scrotal imaging with regard to testicular and extratesticular disorders.
